Question:-- The printer words from the toner cartridge comes out as the hand is rubbed on the printed paper?

Answer:-- There are many possibilities .The most common are as follows:--

First, the fuser assembly may be damaged or at the end of its life. The solution is to replace the fuser assembly. Repairing a fuser assembly is generally not recommended because the fuser is considered a consumable printer part and not worth the time or effort to fix. Second, the toner cartridge may be defective and letting too much toner out at one time. In a black-and-white laser printer, the solution is to replace the toner cartridge. In a color laser printer, only replace the cartridge that is exhibiting the problem. Third, some toner may have spilled in the printer. If so, you'll need to clean it out.

Answer:-- The reason is as follows:--A 50.4 error message on some of the newer HP LaserJet printers indicates a problem with the power supply.-------------

If the printer is connected to a UPS, disconnect it, or disconnect it from a power strip and plug it directly into a wall outlet. A laser printer should never be plugged into a UPS, because the UPS can be damaged by the surges of power required by a printer to keep the fuser assembly warm. If that doesn’t work, make sure that all of the components in the printer are seated properly.this will help.

Question:-- Why i Can't find a driver for a particular operating system?

Answer:-- This is due to many reasons but mostly its due to as follows :--

Whenever the new operating systems are released, new drivers will need to be loaded for your existing printers. Not all printers have a driver for every OS. In these cases, it’s best to consult the printer manual and find out what printers the drivers will emulate. While not all of the functionality of the printer will be available under this emulation, at least basic printing will work. For example, most HP printers will print with the HP LaserJet II driver installed, although specific options, such as duplexing, will not work.

Answer:- -- The cause :-----A 79 error can be the result of a problem with the network print server that services the printer.

To resove the problem:--- When troubleshooting a 79 error, first open the Printer folder from the Start menu on the Print server to make sure there are no jobs pending. A 79 error can also indicate a failure of a printer add-on component, such as an MIO card or a RAM module. All add-ons should be removed and then added back to the printer one by one to determine which module may be at fault.

Turn off the printer. Press and hold the RESUME button, then press and hold the POWER button. Release the RESUME button, then press and release the RESUME button two more times in succession. (youre still holding the POWER button during this). The printer mechanics will move momentarily. You are now in Service mode.

AFTER INSTALLING SUBWOOFER RADIO WILL NOT WORK:

I installed a sub woofer and amp to the factory Delco radio/cd player IN 2001 S-10 Chevy Blazer. Everything is working fine, EXCEPT the lights on the radio/cd player DO NOT work if the key is turned one notch forward to the ON position, or if YOU start the engine.

However,the lights on the radio/cd player DO work if YOU turn the key backwards to the ACC position.

EXPERT'S REPLY:

Where did you connect the Red and Yellow power wires coming off the radio?

Please check this wires connection.

Customer's Reply To This Query:

It was factory radio, we unplug the wiring harness in the back and splice into the speaker wires. Then we simply plugged the harness back in to the radio. I'm assuming we did that correctly because the system itself sounds great, just no lights on that radio when key is in forward on position.

EXPERT'S REPLY:

Try moving the dash dimmer up and see if this makes a difference. Automatic headlights may be coming on which dims the display. Just plug the harness to the head lights back into the headlights switch on the dash.
